ELECTRIC HYDRAULIC BOOSTER

PROBLEM TO BE SOLVED: To provide an electric hydraulic booster, regarding a braking system.SOLUTION: The braking system with this electric hydraulic booster includes: a booster chamber; a booster piston activating chamber; a booster piston located between the booster chamber and the booster activating chamber; and a solenoid valve operably connected to a high pressure source, the booster chamber, and the booster piston activating chamber. The solenoid is movable between (i) a first position whereat the booster chamber and the booster piston activating chamber are in fluid communication and fluidly isolated from the high pressure source, (ii) a second position whereat the booster chamber and the booster piston activating chamber are fluidly isolated from each other and from the high pressure source, and (iii) a third position whereat the booster piston activating chamber and the high pressure source are in fluid communication and fluidly isolated from the booster chamber.
